What are the most reliable firearms that don’t need non 3D printed parts? I plan to print in PA6-CF unless someone can convince me PA12 is better, and I don’t mind projects that need you to tune your settings to hell and back.
I’m looking for a range toy/home defense tool. Handguns are preferred but I don’t mind other form factors. I plan to start with a harlot, but I definitely want something semi auto or slide action, I don’t like the idea of having to load after every shot
I don’t want my address to be associated with 3d2a so I’d prefer projects that don’t need kits or firearm parts, but if it’s absolutely necessary I can get my hands on a barrel liner.
Thanks for the detailed reply bro, I’ll keep everything you said in mind. I don’t mind 22lr but I think I will switch to a barrel liner build. Any recommendations on cheap builds in terms of parts? I’m not sure if this is frowned upon but I don’t want to go down the diy route.
Nothing that goes “bang” is frowned upon :) It all comes down to what you have the skill/funds/resources/interest to build. If you can get 380ACP ammo, my recommendation for an easy, inexpensive build is the Decker 380: https://guncadindex.com/detail/RELEASE-Decker-3.0.1:d . The gun is extremely easy to print and build (easier than most of the 22LR designs). You can get a complete build kit from 3D Print Freedom for $45, but everything except the barrel liner is ordinary hardware that you can buy from a distributor like McMaster-Carr. You can choose between top-feed and side-feed versions, and you can choose between standard semi-auto and forced-reset (what the Decker calls “recoil-assisted-reset”) trigger groups.
If 380ACP is not practical, consider the re-HD22c (from the EZHD22 Megapack: https://guncadindex.com/detail/EZHD22-megapack:1). It’s a relatively easy AR15-style 22LR design. You’ll have to buy barrel liner and hammer and trigger springs – everything else is hardware store line-stock or printable. Build instructions (and printed parts) are a little scattered. It makes more sense if you keep in mind that re-HD22c is a “reinforced” version of the HD22c, which is a “compact” version of the HD22, which is an improved version of the EZ22.
As far as resources, only a 3d printer and as far as funds, under $100 to spend on this project. I was looking at the decker but its kinda ugly lol. I think the urutau would be awesome to build but it’s a bit expensive, and I don’t know if going bullpup for my first build is the best idea (I’d prefer NOT blowing my face off). The re-HD22c looks nice though, thanks for the info on that. I’ll work backwards from the first iteration to get my bearings. If one was hypothetically visiting NJ and wanted to gather materials and build it there, is there anything they should keep in mind? I’ve heard some parts don’t ship there.
I have an Urutau and it cost me about $200 in parts. It also requires buying a full AR-9 barrel or making one via ECM as there is no good way to make safe 9mm barrels using barrel liner. I also had one bolt failure and one OOB that blew up half the gun (both were build problems, not design problems), so I really don’t recommend it to inexperienced builders.
As far as NJ, 3D printed firearms are completely prohibited unless you’re licensed/registered by the state. You can’t legally print a magazine there, much less the rest of the gun. Even distributing firearms STL files is prohibited. All of which is in blatant violation of the 1st and 2nd Amendments, but they don’t care. I’m pretty sure us Arizonans aren’t even allowed into NJ any more - which is fine by me :)
Ah, so an FGC would be thematically appropriate ;). Do you know if a hypothetical new jerseyan were to print a hypothetical firearm in NY and drive it across a hypothetical border to NJ, would she, hypothetically, get in legal trouble if the authorities caught word? Hypothetically, of course. Actually why am i asking you, I should look it up, to satisfy my curiosity. Thanks for all the info/recommendations!
Transporting unserialized firearms into NJ is the same 2nd degree crime as manufacturing - punishable by up to $150k in fines and up to 10 years in prison.
